ROLLER-SKAT E.

SPECIFICATION forming part of Letters Patent No.35,919, dated September 30, 1884.

Application filed June 6, 1884. (No model.)

To all whom, it may concern:

Be it known that I, EDGAR HALL, of Cambridge, in the county of Middlesex, State of Massachusetts, have invented a certain new and useful Improvement inlBoller-Skates, of which the following is a description suiciently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being hadto the accompanying drawings, forming a part of this specification, in which Figure l is a side elevation of my improved skatewith two of the rollers removed;` Fig. 2, a top plan view of the same with all of the rollers removed; Fig. 3, a view showing the forward pair of rollers and clamps in end elevation, thetoe-piece being'represented in vertical transverse section; Fig. 4, a perspective View of one of the clamps detached, its strap being represented as broken off; vand Fig. 5, a vertical longitudinal section of the forward portion of the skate.

Likeletters of reference indicate corresponding parts in the different gures of the drawings.

My invention relates `to the class of skates known as roller or parlor skates; and it consists in a novel construction and arrangeinentoi" the parts, as hereinafter more fully set forth and claimed, by which a more desirable and effective article of this character is produced than is now in ordinary use.

The'natnre and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

ln the drawings, A represents the body of the skate,which is divided into two main portions or sections, B C. Each of these sections is provided with an elongated groove, and with a'narrow projection orv tongue, m, which is adapted to iit a corresponding groove, y, in the side of the opposite section, the two sections being united or clamped together bythe nut and bolt t, by which the body of the skate is rendered extensible.` Jonrnalcd vertically in the outer end of either of said sections there is a stud, D, having at its upper end the inwardly-projecting segment or rack E, and at its'lower end the cross-head K, in which the axle H, carrying the rollers J, is journaled.

-ing riveted to the strap at g.

Projecting horizontally toward the outer end of either of said sections B C there is a stud, L, and journaled to partially rotate on said stud there is a collet or sleeve, M, provided `pivot Z, said toe-piece being adapted to rockl or tilt both longitudinally and laterally, or.

endwise and sidewise. A heel-piece, O, provided with two downwardly-proj ecting flanges,

e, is pivoted at h to the collet M of section B in substantially the same manner as the toepiece N, and provided with an upwardly-projecting ange, P, at either side, for attaching the heel-straps Q. The toe-piece is provided with two elongated transversely arranged slots, R, and with a series of indentations or notches, w, along either side of said slots on the upper side of the toe-piece. A bar, T, having its inner end, b, curved upwardlyv and provided with the lateral projections or studs d, is j ointed to either toe-strap U `by means of the short serrated arm and `joint-pin e, the arm bethe slots B is slightly greater than that of the arms T, and the arms are inserted in said slots from below the toe-piece, being `turned edgewise to permit the entrance of the studs d, after which they are adjusted, as shown in Fig. 3, with the studs resting in the grooves w on either side of the slots.

`It will be obvious that the bars T and arms or levers W form a clamp adapted to grasp the sole or" the boot or shoe of thewearer of the skate, and thus'securely fasten the skate to the foot; also, that the bars T may be moved out or in with respect to the center of the toe-piece to adjust the clamp to any size of boot or shoe.

The object of the toothed collets and racks and their immediately-connected parts is to enable the rollers to be inclined to the longitudinal axial line of the body of the skate in ac- The width of A cordance with the inclination of the heel and A IOU laterally. The'action, however, of the toepiece on the forward pair of rollers will be precisely the reverse of that of the heel-piece on the rear pai'r of rollers, for the reason that the forward rack or segment E stands at the rear of the central axial line of the forward stud D, while the rear rack is disposed forward ofthe central axial line of the rear stud D, the result being that when the heel and toe pieces are both tipped to the left the forward rollers will be correspondingly turned to the left, but the rear ones will be turned to the` right, thereby causing the skate to traverse through the arc of a circle the diameter of which will be great or small in accordance with the degree to which the toe and heel pieces are inclined. i

It will be obvious that by having the rollers adapted to follow the exact line of the curve or circle in which the skater is moving, much less exertion will be required in turning curves on the skates than would otherwise be necessary; also,that the skate may be turned to the right or left .with equal facility.

I do not coniine myself to constructing and arranging the heel and toe pieces in such a manner as to rock endwise; neither do l conne myself to making the body of the skatein two sections or extensible,nor to the use of the adjustable clamp described for securing the toe-piece to the boot or shoe, as all of these features may be varied or substituted by others Without entirely departing .from the spirit of my improvement. The teeth of thesagment E may also be'archedor curved laterally, the teeth on the collet M being correspondingly curved, if desired.

Having thus explained myinvention, what I claim is- 1. In a roller-skate, the bodyA, rendered extensible by the slotsl as, projections m, bolt and nut t, and grooves y, in which said pro-l jections rest. substantially as described.

2. In a roller-skate,the toe-pieee N ,provided with the slots R and grooves or notches w, in combination with the bars T, studs d, jointed levers lW, and straps U, combined and arranged to operate substantially as set forth.

3. The improved roller skate herein described, the same consisting of the sections B C, provided with the studs L, projections on, and slots x, the toe-piece N, provided with the slots R, notches w, and fianges t', the collets M, provided with the teeth fand anges 1^,.the studs D, provided with the toothed segments E and cross-heads K, the axles H,carrying the rollers J, the bars T, provided with thefstuds d, jointed levers W, and straps U, theheelpiece O, provided with the flanges o P and straps Q, and the bolt and nut t, constructed, combined, and arranged to operate substantially as described.
